Application filed February 10,1915. Serial No. 7,444,

San Francisco, in the county of San Fran cisco and State of California, haveinvented new and useful Improvements in Can-Sorting Machines, of which the followingis ,a specification.

The object of the presentinvention is to provide means-for sorting out filledcans of light weight from full weightcans.

In theaccompanying drawing, Figure 1 1s a front view of the-machine, certain of,

the cans being omitted for clearnessyFig. 2 is a similar rear view of the machine; Fig. 3 isaplan view thereof; Fig. 51 is a broken horizontal section on the line 4& of Fig. 1; Fig; 5 is a vertieal-section'on the line 5-5 of Fig. 4; Fig. 8 is plan :view of the feed table ;';Fig. 7 is an end View thereof; F g. 8 1s a-plan v1ew of a weighing pan; F1g. 9

is a side view thereof. 1

Referring to the drawing, 1 indicates the main frame or casting of the machine,to which is secured by bolts 2 a feed table 3, which,at the front edge, is formed with a low wall 4 to guide the cans on the table. To the rear end of the feed table is secured by bolts 6 a standard 7, from the rear end of the top of which extends a guide 8, inn-- mediately over, and spaced from, the rear margin of the table.

9Iindicates a standard, forming part of the main frame, and carrying journal boxes 11 in which rotates a horizontal main shaft 12, carrying a driving pulley 13, and having secured thereto a miter gear 14, which meshes with a miter gear 16 keyed to a vertiealshaft 17 stepped in a bearing in the frame of the machine, extending through an upper portion 18 of saidframe, andcarrying at its upper end a crank 19. Rotatably mounted on said upper portion 18 are two other cranks 21of equal length with the shaft 19, and to the free endsof the three cranks 19 and 21'is' pivoted a link 22, formed integral with which is a standard-23, from" the top of which extends in a longitudinal direction between said table and the guide 8 a pusher-plate 24, having three arms 26 ex tending therefrom in a transverse direction, said plate being concave or rounded between said arms -With each revolutionof thecrank 19,the' operator placesa can on v the rear end of the table at the'time that the pusher plate is in its most advanced position, and, with each succeeding revolution thereof, an arm is wlthdrawn from the front of the can and passed to its rear, and thenthecan is pushed forward on the feed table a distanceequal to that between the arms,

The feed table 3 is formed, near its forward end with a wide opening 27 through its sides, below its top, and the top of the feed ,table'is cut through above said opening to form a narrow passage 28, in the form of an arc of a circle described about a shaft 29 as center.

Formed integral with the miter gear 16 is a gear wheel 31 which meshes with an idle gear wheel 32 rotatable about a vertical shaft 33 having its hearings in the frame, and formedintegral with said latter gear wheel, is a mutilated collar 34: around the shaft 33 and a wrist pin 36 carrying a roller 37., Said roller is adapted to engage any one of a number, here shown as eight, of radially extending recesses 38 formed in the edge of awheel 39, keyed to the shaft29, to,

impart rotation to said shaft 29, and the collar is adapted to engage an adjacent one of a corresponding number of cavities 4:1 in tervening between said recesses to arrest the rotation of the wheel, the parts 37, 38, 3d, 11 forming a Geneva movement. Above the frame a turret 42 is secured to the shaft 29, to which turret is thus imparted an intermittent rotary movement. Extending upwardly from said turret are eight pairs of standards 13, each having at its upper ends bearings for the downwardly directed knife edges of trunnions at extending from opposite ends of a bar 46, from which extends, transversely thereof, or in a radial direction of the turret, scale beams 47. At its inner end each beam carries a weight 48 and at its outer end a bar 49, having at its ends trunnions 51, having upwardly directed knife edges which engage recesses in a frame 52, to which are attached the upper ends of hanger bars 53, which depend through holes in the turret, and are attached at their lower ends to a pan 54, best shown in igs. 8 and 9.

Each pan in succession, in the intermittent rotary movement of the turret, is caused to engage the downwardly inclined face of a wedge 56, formed on the inner portion of the feed table, which wedge forces the pan downward, so that it passes into the opening.

27 in the feed table and is brought to-rest therein, the hanger bars depending through the passage 28 in the top of the feed table.

While the turret is at rest in this position,

a cam is pushed by the pusher plate on to the inner end of the feed table, extending about equally on both sides of the passage 28 through the top of the feed table, and the cylindrical side of the canis received within one of the eight semi-cylindrical cavities L0 in the turret, each cavity having an enlarged upper portion 51 to receive the projecting flange of the top of the can. At the I next movement of the turret, the pan, being no longer under the depressing action of the wedge, rises up under the feed table, and to almost diametrically opposite to each other near to the line between the hangers. The can is held up by the table and the turret until the rearmost'lug 61 has passed from underneath the top of the table and has risen" through the enlarged portion 58 of the passage 28in said top, so that the can is supported by the pan before it has left the edge of the table. 5

The gear wheel 32 meshes with a gear wheel 62loose on the shaft 29, and formed integral with a cam wheel 63 having therein an inner cam groove 64:, and an outer cam groove 66. In said cam groove travel rollem 67, 68, on pins secured to, anddepending from, slide pieces 69, 71,extending at right angles to one another and formed at their outer ends with knuckles 72, 73, which carry pins passing through slots in the ends of short arms of levers 7 4c, 76, pivoted at 77,78,

on the frame of the machine. The inner ends of said slide' pieces are formed with slots 79, 81, having rounded ends, which slots engage a collar 82, which connects the gear-wheel 62 with the cam wheel 63. The diameters of all the gear wheels 31, 32, 62,

are the same, from which it results that each slide piece makes a complete reciprocation with each advance of the can. The upper ends of saidlevers 7 4:, 76 have slotted-pivotal engagements with slides 83, 84;, guided in guides 85, 86, and which carry pushers 87 88. The pusher 88, diametrically oppositev to the feed table, is lower than the pusher 87 which is at an angular distance of threequarters of a revolution therefromt When a full-weight can arrives at the pusher 88, the pan will have been depressed to such a depth that the pusher 88 in its outward movement of reciprocation, engages the can and pushes it from the pan. But when a light weight i can arrives in this posit on, the pan being at a higher level, the pusher 88 its outward movement travels underneath the can and in a groove 89 in the pan. When the light weight can has traveled another quarterof a revolution, it is engaged bythe pusher 87,

which operates at a higher level than the Thus the machine sorts the fullweight and light weight cansf f The provision" of self-centering means upon the pan, namely,- the lugs 59 and 61' concave on their inner sides, I regard as an important feature of my invention for the reason that thereby the can is automatically V 7 so it will hang uniformly from the scale beam.
